W'LL H. VAN GUILDER, OF NEVI RGCELLE, NEW YGRK, ASSIGNOR TO VAN'GUILDER DQUB'LE WALL CG. CNC., 03T EQGHETER, NEVI YORK, A CORPORATION 0F NEW YORK.- .i a

Be it linownthat, iViLnH. VAN Gninonn, a citizen o-thc United States, and residentof New Rochelle, in the county of Westches ter and State of New `York, have invented certain new and useful improvements 'in Molding-Machines, of which the 'following is a specification.

The present invention relates to molding machines, and it has for an object to provide a construction having tivo or more mold walls connected by a frame or clamp which permits relative movement of the Walls so that the machine'may be combined with another machine to produce moloed corners of different angles, or may be used separately to embrace a window or door frame in order that a wall may be formed in close proximity to the window or door frame.

Another object ot the invention is to improve the construction or" molding machines to reduce the cost of manufacture thereoiz and to increase their durability.

To these and other ends the invention con sists of certain parts and combinations of parts all of which will be hereinafter de- Aone end;

scribed, the novel features being pointed out in the appended claims.

In the dra-wings:-

in this instance, are formed offsheet material,`

the lower edge of Which is turned outwardly" at 2 and has an angle iron 3 secured thereto.

rEhe upper edge of this sheet is vbent out-v wardlyl at et and thence upwardly andl out wardly at 5 Lto provide a hopper` eztension.' l

To each wall, tivo uprights 6 are secured,`

preferably their lower ends being riveted at.y

7, and their upper endsbeingextended'- upwardly through the portion 4 of the Wall.

:s Any suitable means may be employed .fornv connecting; the mold Walls so as Ato eHect this instance two pairs'ofbars or slide'sfS" and 9 are provided, one member .of each pair the same pair, and the members-ovf'each ment between them.l I

To the outer faces of the bars 8.and'9," lateral extensions l2 on the uprights 6' are "7o` being` arranged above the other member of) secured by bolts 13,- the bolts being adaptediy to pass through any one of the openingsf 14'I i l so that the desired distance between the mold walls l may be secured. l 4 l Any suitable means may employed' for effecting the relative movement betvfveen. the' Walls. 1n this instance, a l1-shaped membe a 15 has its arms 16 pivoted at 17 to thellovver slide bar 9 while linksv 18 are'pivoted'at I9' to the upper slide bars and at 20 to the'arms ot' the U-shaped member. The swingingrof the aJ-shaped member in one direction moves the walls toward each other, While swinging in the other direction moves' the Walls 41 away from each other. `4

There may also be provided a'score memi ber between the outer mold Walls, thiscorel member beii'ig collapsible and bein in the form oi' two inner walls 21 former? of tivo pieces of sheet metal having their loWer ends 22 turned toward each other in overlapping relation, as Well as their upper ends f 23. Uprights 24 and 25 are securedtolfthe innerv faces of the mold Walls 21 andhave lateral. extensions' 26 at their upper ends secured tothe yslide bars 8 and 9. lQverlapping plates 24a-and 25% ma bersecured to the uprightsQt and 25.7130 c osethe ends of thccor. i i:

To prevent the collapsing of the core member, the uprights 24 may each be prtwided with a beveled lug 27, while the uprights 25 may be provided each with a pair ot beveled lugs 28 lying in vertical planes on opposite sides of the lug 27 on the adj aeent upright 24. ToI operate between the projections or lugs 27 and 28 locking bars 29 are suspended from pivots 30 on the links 18,

lo and have each a pair of laterally-turned flanges 31 at their lower ends for coperating with the lugs 28 to prevent lateral movement of the locking bars.

With the end in View of providing mold 1b chambers, beyond the ends of the mold walls 1 and 21, the molding machine is provided with walls or extensions 32 preferably inv the form of slides guided lbetween the uprights G and the mold wall 1 and between the outwardly-turned portions 2 and 4 on the mold walls 1. These slides or extensions 32 are preferably removable from the machine so that extensions of other lengths ,or shapes may be employed. Means is also provided for securing the slides in their adjusted positions on the machine, this means in thisinstance comprising a hand nut 33 operating on a bolt 34 which projects from the wall through a slot 35 in the plate to permit the removal of the plate without removing the bolt. The uprights 6 are secured in spaced relation from the ends of the walls 1 so that the slide extensions 32 may be moved inwardly within the edge of said mold walls 1.

0n an end of each of the slides 32 reinforcing strips 36 are employed having lateral eyes 37 arranged in vertical alinement, so that the slides on two machines may be connected by a connecting piece 38, shown in Fig. 11, having a hand portion 39 and two pairsv of'hooks or projections 40, each pair connecting two lugs 37 on different machines.

In Fig. 3 two machines are shown connected for forming a corner, the slides 32 at the inner portieri of the corner not being projected from the walls l as far as the slides 32 at the outer portion of the corner.

In this construction, the slide 32 is of greater length than that shown in 2,

and is provided with an additional slot 35 so that the slide may be4 moved inwardly to the extreme limit. Of course the machine with such a slide must be longer than that illustrated in Fig. 2. For forming the air space in the angled corner, an angled core 41 may be provided which has plates 42 projecting from its endsv and resting upon seats 43 formed on the uprights-24 and An angle iron 44 may be arranged within the mold at the outer corner, this angle iron being set upright, and, in rming the cor- 55 ner, thc machine being guided thereby. This plate, the slot opening in the end of the makes it possible with the smallest amount of labor to' secure a corner which is plumb in every respect.

ln Fig. 4, two machines are .connected for forming a chimney, flue or pilaster. The slide 32 of one machine is extended and connected to the unextended slide of the other machine. The other two proximate slides are not withdrawn but are connected by i a pilaster attachment. This attachment comprises preferably a front plate 45 adjustably connected by slots 46 and thumbnuts and bolts 47 with lateral portions 48 on two end walls. Each of these end walls comprises two sections 49 and 50 adjustably 8o connected together, the section 49 having slots 51 and the section 50 having bolts 52 adjustable in said slots 51. The section 50 carries two depending alined pintles 53 which are adapted to enter the alined eyes 37 on the adjacent slide 32. This arrange` ment permits a pilaster or flue to be formed having any suitable width and any suitable depth. The corners of the pilaster are defined by angle irons 44 which are set up- 90 right in the manner described as to Fig. 3. The air space in the pilaster may be formed by a core 54 having plates 42 resting upon the seats 43 at the adjacent ends of the two machines.

For forming flat walls at doorways, windows, or the like, an end Wall 55 may be employed. vThis wall has two pairs of horizonl al slots 56, each Slot having a plurality of recesses 57 in its lower wall. locking members 58 secures the end wall :Tui to the machine, these locking members being in the form of plates having lateral projections 5S) with depending pintlcs G0, the depending pintles being alined. These pintles are adapted to be passed through the eyes 37 on the ends of the slides 32 in the manner shown in Fig. 12 for the purpose of locking the end wall 58 to the slides 32.

ln molding va straight wall, the machine 11.0 is set in position on cross-pieces 61 so that the parts occupy the position shown in Fig. '1. The plastic material is then intioduced into the mold and suitably tampeo, altes' which the operating member 15 is swuhg to move the walls l. away Yfrom each other and the walls 21 toward each other, thus'cxpanding the mold and collapsing the coro. The forming of corners employs two machines connected as shown in Fig. 3, while the forming of pilasters employs two machines connected as shown in Fig. 4.

A molding machine constructed in accordance with this invention'is inexpensive to manufacture and simple to operate. It is not only possible to form straight walls but attachments are provided which permit the machine to i'orm corners. pilasters, and many other wall portions which are impossible to make with an ordinary straight wall ma-I A pa et ioo of the uprights permitting a relative movement between said nprights, and manually i operated means connected with said connection for effecting such relative movement, ot
